Traditional seismic hazard analyses underestimate hazard levels when compared to observations from the 2023 Kahramanmaras earthquakes
Altindal, Abdullah; Askan Gündoğan, Ayşegül (2024-12-01)
A sequence of two major earthquakes, Mw7.8 Pazarcik, and Mw7.5 Elbistan, struck Southeastern Turkey in February 2023. The large magnitudes of the earthquakes and the short time between the two events raised questions about...
A Numerical Investigation of Longitudinal Track–Bridge Interaction in Simply Supported Precast Concrete Girder Railway Bridges
Ozturk, Alper; Baran, Eray; Askan Gündoğan, Ayşegül (2024-08-01)
In railway tracks, additional stresses occur in rails due to interaction between the rail and the bridge superstructure, which is a phenomenon known as track–bridge interaction (TBI). The additional rail stresses (ARSs) de...

Evaluation of the fully coupled WRF and WRF-Hydro modelling system initiated with satellite-based soil moisture data
Duzenli, Eren; Yücel, İsmail; Yılmaz, Mehmet (2024-04-19)
This study comparatively evaluates the skill of the (un)coupled Weather Research and Forecasting (WRF) - WRF-Hydro system supported with satellite-based soil moisture initiation in long-term simulations of hydrometeorologi...
Effect of Wall Size on the Rotation Capacity of Reinforced Concrete Structural Walls
Kazaz, İlker; Sertkaya, Mahinur; Yakut, Ahmet (2024-04-01)
The limiting deformations of RC members used in seismic design and assessment are mainly based on experimental measurements, for which the lack of structural wall tests of large sizes restricts our knowledge on the deforma...
Using System Dynamics to Support Strategic Digitalization Decisions
Kaya, Hazal Deniz; Dikmen Toker, İrem (2024-04-01)
Although digitalization has become a prospect that is counted on for many problems in the construction industry, there have been limited attempts at exploring decision-making processes in construction firms concerning the ...
Liquefaction and performance of foundation systems in Iskenderun during 2023 Kahramanmaras-Turkiye earthquake sequence
ÖZENER, Pelin; Monkul, M. Murat; Bayat, Esra Ece; ARİ, Abdulmuttalip; Çetin, Kemal Önder (2024-03-01)
On February 6, 2023, two devastating earthquakes occurred on the East Anatolian Fault, Turkiye. The earthquakes had severe impacts on civil engineering structures in Iskenderun, Hatay. Reconnaissance studies were performed...
